Notebook of My Mistakes
Extract from "Trainer's Common Mistakes" by Adrian Mikhalchishin
"Thus when a pupil analyzes his own games, he not only tries to understand the position properly, he tries to see new possibilities which he did not consider during the game and eradicates typical mistakes.
In order to keep a registry of mistakes a pupil should use diagrams. These diagrams of mistakes should be put down in a notebook or recorded on the computer, where the type of mistake and the right solution are included.
After some 50-60 diagrams are gathered in the notebook, this system begins to pay dividends as the pupil see his mistakes and is able to correct them, which of course leads to much better results in the tournaments.
The pupil can 'vaccinate' himslef from mistakes before the tournament by a single look at some 2-3 diagrams"
Below is an attempt to log my mistakes, catergorise them and document why they occured.
I will continue to add to this diagram list.
